Title: Automated hair isolation and processing system
Inventor: KING CHRISTOPHER R
IPC: A45C3/00
Filed: 1998-10-30
Abstract: A device comprised of hair-flow-channel guides continuously moved over the surface of the scalp. A track cap of parallel tracks is placed on the head to guide device's movement over the scalp along non-overlapping rows. At the front of the device is a hair-tensioning straightener that pulls hairs perpendicular to the scalp before and during processing. A bend-under assembly, formed by two pinching conveyer belts, facilitates hair exit from the channels by bending scalp-attached hairs beneath the walls of each hair channel.  Intermittent intersection of each channel by an obstructing member isolates one or a few leading hairs for processing and forces trailing hairs to wait their turn for cosmetic processing behind it. Isolated scalp hairs may be cosmetically processed in ways including coloration, cross-section reshaping, hair-extension attachment and removal, and cutting to length according to position along track. Hair extensions removed at one position along a track cap are conveyed to corresponding holding clips and loaded in an order so as to permit their reattachment to the same scalp area.  Hair extensions so held can be channeled and isolated for attachment, as are scalp hairs. A bend-under assembly can be used to draw one or a group of isolated hairs longitudinally through the chamber in which they are isolated facilitating cross-sectional reshaping of hairs or cutting to a preprogrammed length. Intersecting member and cosmetic processing actuation synchronized by computer.

Title: System and method for color palette translation
Inventor: WHITE BRIAN K
IPC: H04N9/64
Filed: 2000-11-08
Abstract: The system and software (1804) of the present invention presents a process for translating a source palette containing TV unsafe colors into a resultant modified palette containing only TV safe colors, while preserving the color trends in the source palette. The software will first analyze a source color palette to determine the TV unsafe colors contained therein. For each TV  unsafe color in the source color palette, the software determines the closest TV safe color by selecting a TV safe color that is the shortest Euclidean distance from the TV unsafe color. The TV unsafe colors are substituted with the calculated TV safe colors and stored in the resultant palette. The software will divide the color space of the source palette into discrete regions, e.g., by Hue (H), by selecting the reference colors as the boundaries of the regions. The initially TV safe color will then be modified in a manner similar to the modifications made on nearby reference colors that were required to make them TV safe. The result will be a resultant palette comprised of only TV safe colors that maintains the color trends of the source palette when perceived by the human eye.

Patent CA-2404472-A1 (CA)
Inventor: KILIAN ANDRZEJ
IPC: C12Q1/68
Filed: 2001-03-29
Abstract: This invention provides methods for determining the genotype of organisms by hybridization analysis and, more specifically, to establishing the relatedness of individual organisms within a species. The present invention provides addressable arrays, comprising diversity panels of nucleic acid molecules, in which the molecules on the array are addressable or uniquely identifiable in some fashion. A diversity panel is the result of a method that can distinguish sequence differences between nucleic acid samples. As taught herein, a variety of methods may be used to generate diversity panels. Subsequent to the generation of the diversity panel, the nucleic acid products of the diversity panel are separated for application onto an array. The separated diversity panel is then delivered onto a substrate to create an addressable array and hybridized with labeled nucleic acids. The genotype of an organism is determined by the pattern of hybridization.

Abstract: Methods and systems for adapting an unstructured mesh to a modeled space. In one embodiment, a surface is defined in the modeled space, intersections of the surface with the elements of the mesh are determined, and new elements within the intersected elements are defined such that one or more of the faces of the new elements are substantially coincident with the surface. For each element which is intersected by the surface, a plurality of points at which the edges of the element are intersected is determined. For each point of intersection, a new node is located at that point and two new elements which incorporate the new node are created. This process is performed for each of the points of intersection so that the intersected element is subdivided into an new elements which include faces that lie substantially on the moduled surface.
